Morphological and molecular characterization of a Sarcocystis bovifelis-like sarcocyst in American beef.

Background: Parasites in the apicomplexan genus Sarcocystis infect cattle worldwide. Assessing the economic importance of each such parasite species requires proper diagnosis. Sarcocystis cruzi, a thin-walled species, infects virtually all cattle.

Revision of Neotrichobia Tuttle & Baker (Acari, Tetranychidae) with ontogenetic development and redescription of N. arizonensis.

The genus Neotrichobia Tuttle & Baker is redescribed with a revised diagnosis. The type species Neotrichobia arizonensis Tuttle & Baker, 1968 is redescribed based on larvae, protonymphs, deutonymphs and adults including the paratype male and deutonymph.

A New Species of (Acari: Tenuipalpidae) from Brazil and Re-Description of (De Leon), the Type Species of the Genus, with DNA Barcodes.

Species of the genus bear a broad subquadrate propodosoma with many large, flattened, lanceolate to ovate dorsal setae. They also bear some plesiomorphic character states, such as the presence of three pairs of ventral setae. Here, we describe Castro, Ochoa & Feres sp.

Identification of the fibroin of Stigmaeopsis nanjingensis by a nanocarrier-based transdermal dsRNA delivery system.

Stigmaeopsis nanjingensis (Ma and Yuan) (Acari: Tetranychidae) is an important pest of bamboo-feeding behavior and silk production by the female adult mites is seriously harmful to bamboo leaves. Due to its small size, silking and cocooning, its management is difficult. This study discusses a fast and easy method for management of the pest by disturbing the spinning behavior.

Antibodies to Toxoplasma gondii in slaughtered free-range and broiler chickens.

The consumption of undercooked infected chicken can be a source of infection for humans and carnivores regarding the zoonotic protozoan parasite Toxoplasma gondii. Furthermore, free-range chickens are sentinels for the presence of T. gondii oocysts in the environment because they feed from the ground.

Photosystem-II D1 protein mutants of Chlamydomonas reinhardtii in relation to metabolic rewiring and remodelling of H-bond network at Q site.

Photosystem II (PSII) reaction centre D1 protein of oxygenic phototrophs is pivotal for sustaining photosynthesis. Also, it is targeted by herbicides and herbicide-resistant weeds harbour single amino acid substitutions in D1. Conservation of D1 primary structure is seminal in the photosynthetic performance in many diverse species.

Long-term cryopreservation of non-spore-forming fungi in Microbank™ beads for plant pathological investigations.

Long-term preservation of experimental fungi without genetic, morphological, and pathogenic changes is of paramount importance in mycological and plant pathological investigations. Several cryogenic and non-cryogenic methods are available for the preservation of fungi, but the methods can be cumbersome, hazardous, expensive, and often not suitable for long-term storage of non-spore-forming (sterile) fungi. A method of preservation of spore-forming fungi in commercially available porous beads (Micrbank™) under cryogenic condition was successfully tested for three non-spore-forming basidiomycetes genera: Rhizoctonia solani (teleomorph: Thanatephorus cucumeris) (n = 19), Ceratobasidium species (n = 1), and Waitea circinata (n = 3), and a non-spore forming ascomycetes, Sclerotinia sclerotiorum (n = 1).

A new species of Tenuipalpus sensu stricto (Acari: Tenuipalpidae) from Brazil, with ontogeny and a key to the known species.

The Cerrado is the second largest Brazilian biome, and is considered to be a "hotspot" due the great concentration of endemic species and high rate of deforestation. Surveys of the mite fauna present in this biome have revealed a great number of new species. In this paper, we describe Tenuipalpus spinosaurus sp.

Brevipalpus phoenicis (Geijskes) species complex (Acari: Tenuipalpidae)--a closer look.

Brevipalpus phoenicis sensu stricto (Geijskes) is redescribed and the species diagnosis established. Two former synonyms of B. phoenicis sensu lato, B.

Simultaneous detection of multiple adulterants in dry milk using macro-scale Raman chemical imaging.

The potential of Raman chemical imaging for simultaneously detecting multiple adulterants in milk powder was investigated. Potential chemical adulterants, including ammonium sulphate, dicyandiamide, melamine, and urea, were mixed together into skim dry milk in the concentration range of 0.1-5.
